This is super important. We started off aiming at the most vulnerable and worked down the list. Now we need to forget that, and vaccinate the so called 'super-mixers'. It's the most efficient way of minimising the risk to the general public from the disease that is out there, and minimising the chances of further strains developing.
There's a lot of talk about making vaccines obligatory for clubs, football, and so on. The most effective move would be to start with pubs, but that's politically out of the question for Boris, we have to maintain the fairytale view of pubs and pub goers as a great British bastion of freedom...
The govt seem to just want to bypass the task of strategising a clear informational campaign, or provide any form of positive incentive, in case it goes wrong. They'll still get where we need to be, but relying on negative reinforcement and restriction will leave a nasty taste in the mouth for some.
